Niklas Schnelle a1ceea67f2 PCI/IOV: Introduce pci_iov_sysfs_link() function
Currently pci_iov_add_virtfn() scans the SR-IOV BARs, adds the VF to the
bus and also creates the sysfs links between the newly added VF and its
parent PF.

With pdev->no_vf_scan fencing off the entire pci_iov_add_virtfn() call
s390 as the sole pdev->no_vf_scan user thus ends up missing these sysfs
links which are required for example by QEMU/libvirt.

Instead of duplicating the code refactor pci_iov_add_virtfn() to make
sysfs link creation callable separately.
